I was stucked on studying this math on factoring problem.

What's the ways use to factor the equation on the left side, so that it becomes the equation on the right side.

Appreciate for any math experts' guide. Thanks

Too broad a queston. Give us the equation.

Tear the equation right where the = sign is and put the left piece on the right.

I'll give you some hints.

1. Multiply through the right side of the equation.
n(a - b)(c - d) = nac - nad - nbc +nbd

2. Use a calculator and figure out what happens if you multiply a number raised to a positive power by the same number raised to the same (but negative) power.

3. Combine like terms from both sides of the equation.

4. Look up the equivalent way to express a term with a negative power, as one with a positive power.

5. Solve using the quadratic equation.

I just ran through the numbers. Lets just say that you won't need to do steps 4 and 5.

That's the easy part... but how do you come up with the 1.5856 and .1577 numbers?
